Several explanations

More beneficial to break links

Mathematically, the expected benefit of breaking/not making new links only depends on the total number of cooperators and defectors, not the number of C and D around an ego

Altruism: making/retaining links even when there is no benefit

Degree changes in initial defectors are no different across conditions

Evolution of cooperation

This seems to occur regardless of initial defector/cooperator position (the same number of C's become D's, and the same number of D's become C's)

D has more links to start

This seems to be the most plausible explanation. Regardless of the network position, initial D's ends up becoming C's in most cases, but not without a cost: many D's tend to lose links first before reaching equilibrium, so networks that have the greatest D degrees may have the least isolation.
